===Cockpit===
[[File:F-22-raptor-16.jpg|thumb|Cockpit of the F-22, showing instruments, head-up display and throttle top (lower left)]]

The F-22 has a [[glass cockpit]] with all-digital flight instruments. The monochrome [[head-up display]] offers a wide field of view and serves as a primary [[flight instrument]]; information is also displayed upon six color [[liquid-crystal display]] (LCD) panels.<ref name=Williams_p10>Williams 2002, p. 10.</ref> The primary flight controls are a force-sensitive [[side-stick]] controller and a pair of throttles. The USAF initially wanted to implement [[direct voice input]] (DVI) controls, but this was judged to be too technically risky and was abandoned.<ref>Goebel, Greg.

Although the F-22 was originally intended to have a helmet mounted display (HMD), this was deferred during development to save costs; the aircraft is currently integrating the Scorpion HMD.<ref name="hatch.senate.gov"/>

The F-22 has integrated radio functionality, the signal processing systems are virtualized rather than as a separate hardware module.<ref>{{cite interview |last=Metz |first=Alfred "Paul" |subject-link= |interviewer-last=Kopp |interviewer-first=Carlo |title=Just How Good Is The F-22 Raptor? |work= |date=September 1998 |publisher=Air Power International |location= |url=http://www.ausairpower.net/API-Metz-Interview.html |access-date=30 June 2007 |archive-url=https://web.archive.org/web/20061207171735/http://www.ausairpower.net/API-Metz-Interview.html |archive-date=7 December 2006}}</ref> The integrated control panel (ICP) is a keypad system for entering communications, navigation, and autopilot data.
